Instead of repeating the same pattern, when sending an IQ get/set packet
and collecting the response
PacketFilter filter = new PacketIDFilter(request.getPacketID()),
PacketCollector collector = connection.createPacketCollector(filter);
connection.sendPacket(reg);
IQ result = (IQ)collector.nextResult(SmackConfiguration.getPacketReplyTimeout());
// Stop queuing results
collector.cancel();
if (result == null) {
throw new XMPPException("No response from server.");
}
else if (result.getType() == IQ.Type.ERROR) {
throw new XMPPException(result.getError());
}
the API got redesigned, so that the above code block can be replaced
with
Packet result = connection.createPacketCollectorAndSend(request).nextResultOrThrow();
